Since [JDK-8348426](https://bugs.openjdk.org/browse/JDK-8348426), when creating the AOT cache with -XX:AOTMode=create, at the very end of normal Java execution, right before we enter the safepoint VM_PopulateDumpSharedSpace, we reset the states of a few Java objects.
Such reset operations can cause the JIT to observe inconsistent states.
While working on a proper fix, this PR is a work-around that disable the JIT during AOT cache creation.
